Permitting a Renovation in DeKalb County: A Starter Guide

Planning a kitchen refresh, bath upgrade, or new deck in DeKalb County and not sure if you need a permit? You’re not alone. The rules can feel confusing, especially with cities inside the county that run their own permitting. In this guide, you’ll learn what usually needs a permit, how e-permitting works, typical timelines and inspections, and how permits affect resale. Let’s dive in.

Start with jurisdiction

Before you sketch plans or call a contractor, confirm who oversees your permit. DeKalb County handles permitting in unincorporated areas, while cities like Decatur, Brookhaven, Dunwoody, Chamblee, and Doraville operate their own building departments. Which office controls your permit depends on where the property sits. Confirm your address with the county or your city first so you file in the right place.

DeKalb County enforces Georgia’s adopted building codes based on International Code Council model codes with state amendments. Cities may have local amendments or additional ordinances, such as tree protection or historic overlays. Because code editions and local rules change, always confirm current requirements with the local permitting office.

Also check for other overlays that may apply to your project. Historic district rules, tree removal permits, zoning setbacks, and HOA approvals can affect design and timing. Getting clarity early saves time during plan review.

What projects need permits

Kitchens

You’ll typically need permits if you move plumbing or gas lines, add electrical circuits, change ventilation, or alter load-bearing walls. Building, plumbing, electrical, and sometimes mechanical permits may be involved. Replacing cabinets or countertops without moving plumbing or wiring is often permit-exempt, but local interpretation varies.

Bathrooms

Moving or adding plumbing fixtures usually triggers a plumbing permit. New or modified electrical and ventilation often need electrical or mechanical permits. Enlarging a bathroom or changing structural walls generally requires a building permit.

Additions and sunrooms

Any increase in conditioned square footage or change to the building envelope requires a building permit and plan review. Expect to provide structural details, foundation plans, and energy-code documentation. Electrical, plumbing, and mechanical trade permits are commonly included.

Decks, porches, and stairs

Most attached or elevated decks require a building permit for footings, framing, and guardrails. Low-to-grade decks may still need a permit, especially if attached or affecting egress. Detached structures can be exempt under some size thresholds, but many jurisdictions require permits once you exceed those limits.

Accessory structures

Small, truly temporary sheds may be exempt, but larger or permanent structures typically require permits and must meet zoning setbacks. Always verify local size thresholds and placement rules.

Garage and room conversions

Converting a garage or unfinished room to living space usually requires building, electrical, plumbing (if added), and mechanical permits. Projects must meet code for occupancy, egress, insulation, and may implicate parking or land-use rules.

HVAC, electrical, and plumbing

Trade permits are standard for HVAC installations, electrical service upgrades or new circuits, and water heaters or other plumbing work. Electrical service changes often require coordination with the utility.

Structural modifications

Removing a load-bearing wall or creating new openings requires permits and, in many cases, engineered details. Plan ahead for plan review and inspections.

Energy and insulation

When you change the building envelope, like with additions or significant window replacements, you’ll usually need energy-code compliance documentation. This is often submitted during plan review.

Homeowner vs. contractor permitting

Owner-builders can sometimes pull permits for work on their primary residence, often with an affidavit. Many scopes require a licensed contractor. Verify licensing and any registration requirements for your jurisdiction.

How e-permitting works

Most DeKalb-area jurisdictions use e-permitting portals. The typical process looks like this:

1. Confirm jurisdiction for your address.
2. Check zoning, floodplain, tree, and historic overlays.
3. Prepare documents: application, scope and valuation, plans, site plan, trade diagrams, energy documentation, and license or owner affidavit.
4. Submit electronically through the correct portal.
5. Pay application and plan review fees.
6. Undergo plan review by building, zoning, and other departments.
7. Address comments and resubmit as needed.
8. Receive permit after approvals and fee payment.
9. Schedule inspections online as work progresses.
10. Complete final inspection and obtain final approval or Certificate of Occupancy if required.

Required documents at a glance

• Permit application with owner or contractor information
• Scope of work and estimated valuation
• Site plan showing setbacks and work location
• Floor and structural plans for additions or structural changes
• Plumbing, electrical, and mechanical layouts for trade permits
• Energy-code compliance documentation when required
• Manufacturer specifications for products like windows or HVAC equipment
• Contractor license and insurance or owner-builder affidavit

Inspections and timelines

Typical inspection sequence

• Footing and foundation before concrete
• Underground plumbing or electrical before backfill
• Framing and rough-in for structural, plumbing, electrical, and mechanical
• Insulation before drywall where energy code applies
• Final trade inspections
• Final building inspection and final approval or Certificate of Occupancy

Review and scheduling timelines

Plan review times vary by scope and backlog. Simple trade-only permits can be days to a couple of weeks. Additions and structural projects can take multiple weeks, especially if resubmissions are needed. Inspection scheduling is online in many jurisdictions and can range from next-day to several business days.

Fees

Fees are often based on the cost of work or set as flat fees for specific permit types. Separate plan review and trade permit fees are common. Check the current schedule for your jurisdiction before you submit.

Renovating before selling

Permits and final approvals protect you at resale. Lenders, appraisers, and title companies may flag unpermitted work, which can delay financing or affect value. Appraisers may exclude unpermitted square footage from the appraisal. Insurance claims related to unpermitted changes can be complicated.

If you discover past work without permits, most jurisdictions offer retrospective permits. You may need as-built plans, penalty fees, and corrective work to meet current code. For some sellers, credits or escrows can help address costs to bring work up to code.

To reduce friction when you list, complete final inspections and keep records. Provide buyers with permit numbers and final approvals. Permits and close-out documents increase buyer confidence and can keep your closing timeline on track.
